For our North American trips, we use the 2025 Cervélo Áspero—a fast, responsive, and versatile bike that’s built for both road and mixed-terrain adventures. Outfitted with 32mm tires for road routes, or 40mm GravelKings for gravel, this bike adapts to the ride. With SRAM electronic shifting, confident handling, and a lightweight frame, it’s ideal for long days in the saddle, big climbs, and high-speed descents. Our guides have tested it extensively and agree—it delivers a smooth, capable, and fun ride whether you're spinning through Tucson or climbing in the Montana mountains. Available sizes: 48cm, 51cm, 54cm, 56cm, 58cm, 61cm.

Bring your cycling shoes, helmet and pedals. It’s completely optional, but we also suggest bringing your saddle to immediately feel right at home on a new bike. If you have a personal Garmin, Wahoo or other bike computer, feel free to pack that with a mount. On the first day of your trip, our guides will help get your rental bike ready to ride and ensure that the bike fits well. Keep in mind that a rental bike’s geometry will likely be a little bit different than what you’re used to, but you’ll get used to it quickly, and we’ll make sure it fits properly before your first spin.
